Description

Nginx dynamic upstream(http & stream) use http json

add(server,backup,down,weight,max_conns,max_fails,fail_timeout)

server : must setbackup noset : falsedown noset : falseweight>0 else : 1max_conns>0 else : 0max_fails>0 else : 1fail_timeout>0 else : 10 

del(name,server,backup,down)

name/server must set at least onebackup noset : falsedown noset : false 

edit(name,server,backup)

name/server must set at least onebackup noset : falseothers can modify, noset no modify 

Example:

List:

{"method": "lst"} 

Add:

{"method": "add","params": [{ "http":{ "upsname" : "upsname", "peers":[{ "server":"10.0.2.11:9900", "weight":10, "max_conns":0, "max_fails":3, "fail_timeout":60, "backup": true , "down": false },{}]}},{ "stream":{ "upsname" : "stream_ups", "peers":[{ "server":"10.0.2.11:9900", "weight":-10, "max_conns":0, "max_fails":3, "fail_timeout":60, "backup": true , "down": false },{}]}}]} 

Del:

{"method": "del","params": [{ "http":{ "upsname" : "upsname", "peers":[{ "name":"[::1]:10001", "server":"localhost:10001", "backup": false, "down": false },{}]}},{ "stream":{ "upsname" : "stream_ups", "peers": [{ "name":"[::1]:10001", "server":"localhost:10001", "backup": false, "down": false },{}]}}]} 

Modify:

{"method": "edit","params": [{ "http":{ "upsname" : "upsname", "peers":[{ "name":"127.0.0.1:10001", "server":"localhost:10001", "backup": true, "weight":10, "max_conns":0, "max_fails":3, "fail_timeout":60, "down": false },{}]}},{ "stream":{ "upsname" : "stream_ups", "peers":[{ "name":"127.0.0.1:10001", "server":"localhost:10001", "backup": true, "weight":-10, "max_conns":0, "max_fails":3, "fail_timeout":60, "down": false },{}]}}]} 

return Result(list)

return Result(add/modify/del)

success(code == 0)

{"code": 0,"message": {"success": 0,"failed": 4}} 

failed(code != 0)
